Fleet Command, previously labelled as Jane's Fleet Command, is a real-time tactics naval warfare simulation computer game released in 1999. It was developed by Sonalysts Inc. and published by Electronic Arts. The game licensed parts of Jane's Information Group's military information database, which was used as an in-game "Jane's Library", reference material that the player could refer to while in-game. Jane's also licensed to EA the "Jane's" name and the "Jane's Combat Simulations" logo, and the game was marketed under the "Jane's" name, much like the previous "Jane's Fighters Anthology", also published by Electronic Arts. The game was also released in a three-game "Naval Combat Pack" along with 688 and F/A-18 Hornet. The game supported 3D rendering by either D3D or 3dfxGlide, but not OpenGL or software rendering. Fleet Command was written primarily for the use of the now defunct Voodoo brand video cards that used Glide. D3D rendering is slower than the native 3dfxGlide rendering of the same map, even when using the newest D3D-capable cards. The game was written for Windows 98, although it would run on Windows 95. On Windows XP, the game had serious stability and installation issues until the 1.34 and 1.38 patches and the XP installation utility/patch.
